Re: Dielectric absorption (was LED Charge Indicator)

Dielectric absorption was demonstrated dramatically when I unrolled a defibrillation capacitor (36uF 5kV) and sparks were developing giving me little shocks. Tearing the dielectric and film/foil gave rows of tiny sparks captured with my digital SLR camera.

.....Note that many caps, like Peter's, will recharge if left open after being charge for a long time...
